摘要
A new synthetic procedure has been developed to obtain single crystals of the square planar complex Pt(II)[2,2′-bpy)(NCO)2] in which the two pseudohalide ligands occupy cis positions. The results of a complete X-ray diffraction study are reported, and confirm the N-bonding of the cyanate moiety in the solid. Both solid and solution infrared data are reported for this complex, in particular the characteristic signature of the NCO ligand. The relationship between the spectroscopic and structural data is discussed in detail. In addition, 13C NMR data are reported for this complex in N-methyl pyrrolidone, and confirm the persistence of N-bonding of the NCO group in solution. © 1990.
